KNITTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 461,212, dated October13, 1891.

Application filed October 14, 1890. Serial No. 368,113. (No model.)

To all whom it may concern.-

- Be it known that we, NICHOLAS J. WVIN- LUND, a subject of the King ofSweden, and EDWARD MOSHERRY, a citizen of the United States, bothresidents of Rockford, in the county of Vinnebago and State of Illinois,have invented certain new and useful Improvements in Knitting-Machines,of which the following is a specification.

The object of this invention is to automatically throw into actioncertain needles or to move them out of action during the processofknitting; and it consists of a disk pattern-wheel which is so locatedas to re volve around the needle-cylinder and is provided with groovesin which are located subacks, so that in their movement of thepattern-wheel they'are moved radially for the purpose of moving thejacks into or out of engagement with their operating-cam, which willthrow the needles into or out of action.

In the accompanying drawings, Figure 1 is a plan view of aknitting-machine embodying our invention, in which a portion is brokenaway to show the upper surface of the pattern-wheel. Fig. 2 is atransverse vertical section through the needle-cylinder, showing themechanism for throwing the needles into or out of action and the cam forraising or lowering them during the process of knitting. Fig. 3 is asection similar to Fig. 2, which clearly shows the position of theneedles,

- jacks, and sub-jacks when the needles are out of action.

This invention relates to the class of knitting-machines known as thecircular variety, and consists of a needle-cylinder 1, standing in avertical position, which has its outer surface longitudinally groovedfor the reception of needles 2, jacks 3, and sub-jacks 4 and 5. A ring 6is slipped over the upper end of the cylinder, and when in positionholdst-he needles in working position in their grooves.

From the lower end of the needle-cylinder a base 6% extends laterally,which has a portion of its upper surface provided with radial grooves 7,in which are located the subjacks 4. The needle-cylinder is supportedupon a suitable frame 8. Aneedle-operating cam 9 is located within thecentral opening of the needle-cylinder and has its outer sur face formedwith an annulargroove 10, a portion of which is irregular in form, sothat in its rotation or oscillation the irregular portion coming incontact with the needles will raise and lower them during the process ofknitting. This cam is held in position by a collar 11, secured to theoutside of the laterally-extending base, and a toothed wheel 12 issecured to the lower end of the cam,which meshes with the teeth of asimilar toothed wheel (not shown,) from which motion is iniparted to thecam. An inward projection 13 is formed on the jacks and extends throughvertical openings 14, extending through the needle-cylinderand entersthe grooves of the cam, and by means of which the needles are operatedas the upper ends of the jacks engage the 'lower ends of the needles,and thereby any movementimparted to the jacks in their lengthwisedirection will be transmitted to the needles.

The pattern-wheel l5, employed in connection with our construction ofneedle-cylinder, ,7 5

is of disk or plate form, and is located around the needle-cylinder insuch manner that the cylinder forms the center around which the wheelrevolves. This wheel is formed with a rim 16, rising from its outer edgeon its upper surface, and is cut in saw -toothed form. An'intermittentrotary movement is imparted to the wheel by a dog 17, pivoted at one endto a bar 18, which is pivoted between its ends to a stationary support19. A rotary disk 20 has pins 21 projecting from its inner face, and aseach pin comes in contact with the lower end of the bar 18 the upper endwill be moved, carrying the dog with it, and in its movement the freeend of the dog will engagethe teeth of the pattern-wheel, moving itforward one notch, and after the pin has left its engagement with thearm 18 a spring 22 will retract the dog, ready to engage the next tooth.The upper and under side surfaces of the pattern-wheel 5 The thesub-jacks which play in the radial grooves formed in the upper surfaceof the laterallyextending base, and have their inner edges bent atsubstantially right angles to their main portion, and enter a notch 25,formed in the lower end of the jacks, so that a connection is formedbetween the needles and pattern-wheel.

A disk 26 is placed over the pattern-wheel so as to fit within therecess formed by the uprising ratchet-ring, and its inner edge is formedwith a depending fiange 27, which rests upon the laterally-extendingbase in such a manner as to permit the pattern-wheel to revolve beneathit. A portion of the upper surface of the disk 26 is provided withradial slots 28, in which sub-jacks 5 move lengthwise, dependingprojections 29, formed on the under edge of the sub-jacks, extendingthrough slots 30 in the disk 26, and entering the grooves in the uppersurface of the patternwheel. The sub-jacks have the same connection withthe jacks and needles as has been described in relation to sub-jacks 4.A plate 31 is placed overthe disk 26 to hold the subjacks 5 in theirgrooves.

In the rotation of the pattern-wheel the sub-jacks will follow thegrooves therein, and when a switch is encountered the correspondingsubjack will move lengthwise, and should the movement be outward thesubjack willmove the jack with which it is conneoted outward, causing itto become disengaged from its raising and lowering cam, thereby holdingthe needles out of action, and when the reverse movement is imparted tothe sub-jacks by the pattern-wheel the projection upon the jack willenter the cam-groove, when the jack will be raised and lowered, carryingthe needles with it during the process of knitting. In this instance wehave connected only the fashioning-needles used to form the heel and toeof a stocking with the pattern-wheel, one half having a connection withthe under side of the wheel and the others with the upper side, and eachneedle has a separate groove, so that its movements are independent ofthe others, and can be thrown into or out of action at any time itbecomes necessary.

The grooves of the pattern-wheel can be varied according to the style ofthe knitting to be produced, and more or less needles can have aconnection with the pattern-wheel in a like manner. It is alsoevidentthata series of these pattern-wheels could be arranged one abovethe other, each to operate a portion of the needles, and otherarrangement of devices can be employed to impart an intermittent rotarymovement to the pattern-wheel.

We do not claim, broadly, in this application the sub-jacks located andmoving radially and having a connection with the jack, in the mannershown and described.

\Ve claim as our invention- 1. In a knitting-machine, the combination ofa needle-cylinder, needles located therein, jacks and sub-j acks, and adisk pattern-wheel located outside of and around the cylinder, operatingupon the needles through the jacks and sub-jacks to throw them into orout of action, said pattern-wheel provided with an independentcam-groove for each fashioningneedle, and the sub-jacks capable of aradial sliding movement, substantially as set forth.

2. In a knitting-machine, the combination of a needle-cylinder, needleslocated therein, a disk pattern-wheel located outside of and around thecylinder, operating upon the needles to throw them into or out ofaction, said pattern-wheel provided with an independent cam-groove foreach fashioning-needle, and means for imparting movement to thepattern-wheel, substantially as set forth.

3. In a knitting-machine, the combination of a needle-cylinder, adouble-faced pattern- 7 located within the needle-cylinder for raisingor lowering the needles during the process of knitting, substantially asset forth.

5. In a knitting-machine, the combination of a needle-cylinder having alaterally-extending base, which is provided with grooves on its uppersurface, jacks and needles, a pattern-wheel located over the base, saidpatternwheel provided with an independent camgroove for eachfashioning-needle, and sub jacks located in the grooves of the base andengaging the pattern-wheel, said sub-jacks having a connection with thejacks and the jacks with the needles,whereby the movement of thepattern-wheel is transmitted to the jacks, substantially as set forth.

6. In a knitting-machine, the combination of a needle-cylinder in whichare located needles and jacks, a double-faced pattern-wheel locatedoutside of and around the cylinder, and sub-jacks having a connectionwith the wheel", some located above the wheel and some below, saidsub-jacks having a connection with the jacks for throwing them into andout of engagement with their operating-cam, substantially as set forth.
